A new tool, the System for Observing Behavioral Ecology for Youth in Schools (SOBEYS), accurately records physical activity (PA) and behavioral support in schools. This enables better understanding of PA interventions.
Area of Science:
- Behavioral science
- Public health
- Educational psychology
Background:
- Physical activity (PA) interventions in schools are promising but lack concurrent data collection for PA and behavioral support.
- Existing observation systems do not capture the behavioral ecological context of PA.
- There is a need for a validated instrument to assess behavioral support during school-based PA.
Purpose of the Study:
- To develop and validate the System for Observing Behavioral Ecology for Youth in Schools (SOBEYS).
- To create an instrument capable of recording behavioral support for PA within a school setting.
- To enable concurrent measurement of PA and behavioral support.
Main Methods:
- Behavioral categories for prompting and reinforcement of PA were developed by experts in 2013.
- The SOBEYS system was implemented in a suburban junior high school (N=1452) during spring 2014.
- The system was refined through multiple field trials.
Main Results:
- The SOBEYS instrument successfully recorded visual/verbal prompting, verbal/nonreinforcement, and token reinforcement.
- Construct validity was established.
- Acceptable interobserver agreement was achieved (>90% with kappa values from 0.22 to 0.94).
Conclusions:
- Trained users can reliably use SOBEYS to record behavioral support for PA.
- SOBEYS integrates with existing PA observation instruments.
- This tool facilitates the assessment of PA context and quantity alongside behavioral support.
